It really depends on the sales reps. I've always had outstanding service at the Fountain Valley one. Only time I had a negative experience was the one an Orange. This Hispanic "salesman" with a scar on the back of his head was being an utter jerk about doing DROS work. Made some excuse that their computers were already shut down with 2 more hours left til store closing. Worst part is, afterwards, he continues to try to make a sale with someone else.
Hard to monitor all employees at a chain. In hindsight, I should have taken his name and reported him, but me and the guy I was trading with was in a rush to find another place to transfer before all stores were closed.
